13 Claims.

This invention relates to improvements in gauging devices for shoemachines and is illus trated as embodied in an edge gauge mechanismsuitable for use in a channeling machine intended for operating uponso-called orthopedic insoles. v

Orthopedic insoles, so-called, are made with lateral extensions or wingsat their inside shank portions or with extensions at both the inside andoutside shank portions of the insoles, and in the manufacture of shoeshaving such .insoles the extensions or wings are laid back or moldedagainst the sides of the lasts so that they will serve in the finishedshoes to support the arches of the feet.

Edge gauges of channeling machines are commonly adjustable to produce afeather of varying width. For example, the feather may be 2/16 of aninch wide at the outside ball, -fe of an inch at the toe and inside balland sof an inch at the shank; however, the adjustments provided for areof such relatively small variations of width that they cannot be used tocare for the wide extensions to be encountered at the Shanks oforthopedic insoles. Accordingly, some means must be provided forremoving the edge gauge from the path of the extension or wing whilechanneling in the shank section of this type of insole. To this endUnited States Letters Patent No. 1,482,140, granted January 29, 1924 onthe application of E. E. Orr, discloses a treadle-controlled adjustableedge gauge which is adapted to be adjusted to three positions to varythe Width of feather and also to be moved to a fourth position where thegauge is lowered below the surface of the work support and out of thepath of the extension. The edge gauge disclosed in that patent isprovided with the customary limiting stops for indicating the threepositions of the edge gauge used in channeling non-orthopedic insoles,These limiting stops arrest the movement of the edge gauge in threedierent positions and as a treadle transmits movement in only twodirections, i. e., up and down, and hence is subject to only two limitsor stops, the Orr machine is provided with two separate treadlemechansms for operating the edge gauge. Inasmuch as many channelingmachines now on the market are provided with several treadle mechanismsfor controlling dien ent elements of the machine, such for example, asthe work support and the means for varying the length of the feed strokeof a selected knife, the addition of two more treadles creates acondition which is necessarily confusing to an operator.

It is an object of the present invention to provide an improved edgegauge operating mechanism which is simple and efficient in operation andin which a single control member is 1938, Serial N0. 197,436

utilized to adjust the gauge relatively tothe cutting knives to regulatethe width of the feather that is being cut by the knives and also tocontrol automatically heightwise movement of the edge gauge with respectto the work upon movement of the edge gauge to a predetermined positionof adjustment. As herein illustrated in a machine for channelinginsoles, this invention may be recognized in the combination of a worksupport, an adjustable edge gaugelocated adjacent to the Work supportand arranged to overlie the work support in certain positions ofadjustment and a manually operable control member which is adapted toadjust vthe edge gauge transversely to the line of feed, and also tocontrol the heightwise movement of the edge gauge with respect to thework upon movement of the edge gauge to a predetermined position ofadjustment With the above and other objects in view the invention willnow be described with reference to the accompanying drawing and will bepointed out in the appended claims.

in the drawing,

Fig. 1 is a plan view of a portion of a channeling machine showing theimproved edge gauge construction;

Fig. 2 is a View in elevation of the mechanism shown in Fig. 1 with theedge gauge in its lowered position-wherein it is located below thesurface of thework support; and

Fig. 3 is a view in elevation similar to Fig. 2 with certain partsbroken away showing the edge gauge in its elevated position.

Referring to the drawing, the invention is therein shown as embodied ina machine of the type disclosed in United States Letters Patent No.984,773, granted February 2l., 1911 upon the application of W. C. Meyer.The illustrated machine comprises a rotary work support lil, achanneling knife I2 for cutting obliquely into the substance of aninsole Ii so as to form a channel and an inner lip, an edge-slittingknife i6 for cutting inwardly from the edge of the insole in a planeparallel to the face of the sole to form an outer lip and a feather, andpresser gauges I8 and 20 to limit the depth to which the knives enterthe work. The machine is further provided with an adjustable slide 22which is mounted in a guideway 2li located below the plane of the tablelli. The slide 22 has a laterally eX- tending head portion 23 which hasa groove therein in which is slidably mounted the depending shank 25 ofan edge gauge 2t. The edge gauge 26 is normally biased downwardly intoengagement with the head 23, in which position it will be located belowthe surface of the work support, by a spring 28 which is connected atone end to the edge gauge 26 and at the other end to a pin 2Q extendingfrom the slide. The

slide 22 is moved relatively to the work support to move the gauge 26transversely of the line of feed by a segmental gear 3l) which mesheswith gear teeth formed in the side of the slide 22, and which is fast tothe upper end of a rock shaft 32 journaled in a bracket 36. rihe lowerend of the rock shaft 32 is connected to a crank arm 36 having a forkedend which receives a block 38 pivoted to a rotatably mounted disk ci@having Va depending spindlev which is journaled in a bracket 42. Oneextreme position of the gauge is determined by a pin "il which iscarried by the disk 40 and projects into a recess i3 in the bracket`4t2, and the other extreme position of the gauge is determined by a pin5i which also proljects into the recess 43 and is carried by a collar 39clamped to the disk d6. Connected to the ing a latch l5 thereon fordetermining the intermediate positions of the edge gauge by engagementwith stops on the bracket ft2 and a collar 31 clamped to the bracketF42. rihe latch together with the pin 'i depending from the disk 4U andthe` pin lli extending inwardly from the collar 39 determine the variouspositions or" the edge gauge in a manner similar to the correspondinglatch 2li and pinsl i9 and 22 in United States Letters Patent No.1,030,802, granted June 25, 1912, upon the application of F. E.Bertrand, which shows a four position gauge adjusting mechanism foradjusting an odge gauge in a machine of the type disclosed in the patentto Meyer No. 984,773 referred to above. The brackets 3d and dil areattached to a horizontal projection Q6 on the work support slide.Operation of the hand lever lll rotates the Il@ which in turn rotatesthe lever 3% and gear Sil to move the slide relatively to the worksupport Ill.

The edge gauge is raised from an out of the way position below thesurface of the work support where it is in engagement with the head 33to an operating position above the surface or the work support by alever ist iulcrumed upon a pin 49 secured in the arm 3e. The lever ithas an end portion 5l which is disposed below the edge gauge shank 25and is curved so as to underlie the shank throughout the range ofmovement of the arm 315. Formed upon the other end of the lever t8 at alocality adjacent to the disk 4G is a cam surface $3 which is adapted tobe engaged by a cam surface :"5 formed upon a cam plate 50 fast to ablock 52 attached to the disk Ml. Upon engagement of the cam surface 55with the cam surface 53, the lever lil is rotated in a clockwisedirection about its pivot, as viewed in Fig. 3, raising the edge gaugeabove the surface of the work support. The cam plate extends over thatsegment of the disk ttl which corresponds to the positions of the gaugewhen regulating the channeling of regular insoles thus holding the gaugein its raised work engaging position throughout that range of movementbut terminates short of the portion of the disk which corresponds to theposition to which the edge gauge is moved by the lever llt when a tabportion such as l5 o the illustrated insole is encountered, thuspermitting the gauge to be moved down-f wardly under the urging of thespring 23 to enable the tab portion to pass over the gauge.

In channeling an orthopedic insole in the illustrated machine, the gauge2S is adjusted to the three selected gauging positions in the usualmanner by the lever Ml while the outer shank and ball portions are beingoperated upon. When the tab portion is reached, the hand lever is movedto a fourth position, with the result that the cam plate is moved fromabove the lever 48 allowing the latter to ltilt in a counterclockwisedirection and the gauge 26 to drop below the level of the work support,thereby enabling the tab to pass over the gauge as the inner shankportion is channeled in the usual manner.

It is evident from the above description, that by placing the means forraising and lowering the edge gauge under the control of the hand leverwhich adjusts the edge gauge transversely of the lineof feed, applicanthas greatly simplined the control oi the edge gauge, as in operating amachine equipped with an improved gauge mechanism built in accordancewith the teachings of this application, all that an operator need do tocontrol the gauge is to shift the conventional hand lever through theusual positions when channeling portions of an insole where the edge isnot obstructed by a tab and when a tab portion is encountered, he needonly move the hand lever to another position where the gauge will beautomatically lowered out of the path of the tab permitting that portionof the insole to be channeled.
